Musannaf Ibn Abi Shaybah 35904 — Taking women on campaign

It is narrated from Sa'id bin Amr that Sayyidah Umm Kabshah (may Allah be pleased with her), a woman of Banu Udhrah, said to the Prophet (peace and blessings be upon him): "O Messenger of Allah, give me permission to go along with such-and-such army." He (peace and blessings be upon him) said: "No." She said: "O Messenger of Allah (peace and blessings be upon him), I am not going with the intention of fighting; I want to go in order to dress the wounds of the sick and injured and to give water to the sick." He (peace and blessings be upon him) said: "If this were not to become a custom, with people saying that so-and-so woman went out on jihad, I would have given you permission. But stay where you are (do not go along)."
